Classification and Birational Equivalence of Dimer Integrable Systems for Reflexive Polygons
Minsung Kho, Norton Lee, Rak-Kyeong Seong
Brane tilings are bipartite periodic graphs on the 2-torus and realize a large family of 4d N=1 supersymmetric gauge theories corresponding to toric Calabi-Yau 3-folds. We present…
Dimers for Relativistic Toda Models with Reflective Boundaries
Kimyeong Lee, Norton Lee
We construct dimer graphs for relativistic Toda chains associated with classical untwisted Lie algebras of A, B, C, C, D types and twisted A, D types. We show that the Seib…
A Match Made in Heaven: Linking Observables in Inflationary Cosmology
David Stefanyszyn, Xi Tong, Yuhang Zhu
Cosmological correlation functions of inflaton and graviton perturbations are the fundamental observables of early universe cosmology and remain a primary target for observations.…
Birational Transformations on Dimer Integrable Systems
Minsung Kho, Norton Lee, Rak-Kyeong Seong
We show that when two toric Calabi-Yau 3-folds and their corresponding toric varieties are related by a birational transformation, they are associated with a pair of dimer models o…
Holographic Entanglement Entropy in the FLRW Universe
Toshifumi Noumi, Fumiya Sano, Yu-ki Suzuki
We compute a holographic entanglement entropy via Ryu--Takayanagi prescription in the three-dimensional Friedmann--Lemaître--Robertson--Walker universe. We consider two types of ho…
Can Horndeski Genesis be Nonpathological?
Han Gil Choi, Pavel Petrov, Masahide Yamaguchi
We present a minimal setup within the framework of Horndeski gravity that can describe a nonpathological Genesis scenario. Our setup allows for a fully stable transition to the kin…
